What is the heaviest galaxy in the universe?

Answer 1

The largest (and most massive) galaxy that we know of is the galaxy IC 1101 at the center of the cluster Abell 2029.

In general, the most massive galaxies are the elliptical galaxies at the center of galaxy clusters, known as BCGs (or Brightest Cluster Galaxies). In a cluster of galaxies, galaxies tend to fall into the center, making a very massive galaxy at the core.

One of the largest BCGs known is the galaxy IC 1101 at the center of the cluster Abell 2029, which has a stellar mass of about 100 trillion (10^14) times that of the Sun.

There could be larger galaxies in the Universe, IC 1101 is just the largest we have found so far.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
